[Hawk Bit (Kouji)] Older Brother (Magical Girl) vs Little Sisters (Lesbian Succubi Monsters) [Black Grimoires]

A newly transformed big sister—once the older brother—faces off against her own little siblings Claviel and Mystiel, a pair of sadistic succubi who worship nothing but pleasure. Desperate pleas to stop dissolve into shuddering bliss as the demon girls torment every sensitive spot from armpits to palms, their relentless teasing rewiring body and mind until even her breasts become instruments of ecstasy. What begins as a magical girl's last stand ends with heart-eyed surrender, the broken heroine eagerly offering herself as the sisters' devoted minion, hungry to repay them with her own slutty holes.
